-bash completion needs to be rewritten from the ground up.
----------------------------------------------------------
-
-bash completion really needs to be rewritten from the ground up, using all of
-the features available in bash 4.1+ and without regard for compatibility with
-earlier versions.
-
-At that time, it should be split into multiple files for easier source
-management. Whether or not it is actually installed on the destination
-computer as separate files is a matter for future debate.
-
-If it were installed as tens or even hundreds of files, each of which had to
-be opened to decide whether it should be sourced in its entirety, that could
-prove very expensive on some systems.
-
-Alternatively, a master file could decide which of the individual completion
-files should be sourced. In that way, we wouldn't need to open extra files
-just to ascertain that the commands for those functions aren't on the system,
-anyway.
-
-A further alternative is that a build process be created, which would
-concatenate the various files into a single completion file, similar to what
-we have now. This option is my least favourite, because a system with a lot of
-packages installed currently has to deal with sourcing over 200 kB of bash
-code for each invocation of an interactive shell.
-
-An even better alternative would be if bash supported dynamic loading of shell
-functions (in the manner of zsh), but I don't believe there are any plans to
-add this feature.
